Qualcomm Explains Quick Charge 5 In Details


Quick Charge 5

Yesterday, Qualcomm announced the launch of Qualcomm Quick Charge 5, the fastest commercial charging technology for Android devices. Compared with the previous generation, this platform can not only provide unprecedented charging speed and efficiency improvement for smartphones but also supports a series of new battery technologies, accessories and safety features.

Qualcomm said that Quick Charge 5 is expected to become the first commercial fast charging platform that provides charging power of more than 100W for smartphones. It can help users to charge their phones from 0 to 50% at 4500mAh in only 5 minutes. It will take only 15 minutes to fully charge.

Utilizing Qualcomm Battery Saver battery health management and the new Qualcomm adapter power intelligent identification technology, Quick Charge 5 also achieves excellent charging efficiency and helps users extend the battery life of the terminal.

Performance and efficiency

The performance of Qualcomm Quick Charge 5 is significantly improved compared to the previous generation platform. For example, the charging efficiency is 70% higher than that of Quick Charge 4. Plus, the output power is 10 times that of Quick Charge 1. The solution supports 2S battery and 20V power output.

The charging speed of Quick Charge 5 is 4 times that of the previous platform. In addition to supporting extremely fast charging, Quick Charge 5 also supports excellent safety features. Among them, we cane mention 12-level voltage, current and temperature protection, 25V USB input overvoltage protection and 30V or more external charging power control. Its operating temperature is also 10 degrees Celsius lower than Quick Charge 4. Quick Charge 5 supports dual/triple charging technology, adaptive input voltage, fourth-generation optimal voltage intelligent negotiation (INOV4) algorithm, Qualcomm Battery Saver battery health management, and new Qualcomm adapter power intelligent identification technology. The above technologies will work together to maximize the charging efficiency. Plus, they will enhance safety and help extend the battery life of the user terminal.

To achieve the best performance of Quick Charge 5, Qualcomm also introduced the latest next-generation top power management integrated circuits (PMIC) – Qualcomm SMB1396 and Qualcomm SMB1398. By supporting 1SnP and 2SnP batteries, dual-channel wired and wireless charging, adaptive operation based on power input (3-level Buck and DIV/2) and scalability (using a master-slave architecture to provide higher power), Qualcomm SMB1396 and Qualcomm SMB1398 are designed to achieve a maximum charging efficiency of over 98%. Not only that, they also support an input voltage above 20V operating mode to adapt to the highest power input for wireless and wired charging. The Qualcomm SMB1396/SMB1398 are available now.

Ecosystem and wide range of uses

Quick Charge 5 can handle various charging methods of mobile terminals. It is backward compatible with Quick Charge 2.0, 3.0, 4, 4 +. And smartphones that are already on the market with the Qualcomm Snapdragon mobile platform support it. The solution supports the charging power of more than 100W. It uses the same pin area as the previous generation 45W solution. This reducing the need for users to purchase additional Quick Charge certified accessories for multiple terminals. The optimized Quick Charge 5 can make full use of USB-PD and Type-C technologies to meet the needs of future Android terminals. The compatibility of Quick Charge 5 with industry standards such as the USB Type-C protocol also helps users benefit from the native scalability of Quick Charge 5 and extend it to other terminals.

Currently, Quick Charge 5 is sampling to customers. We are expecting it to be available with commercial terminals in the third quarter of 2020. Snapdragon 865, Snapdragon 865 Plus, and future top and high-end Snapdragon mobile platforms can support Quick Charge 5.
